Application 'filed August 18,

To all whom t may concern Be itl known that' I, NATI-IAN C. CHAP- VMAN, citizen of the United States, residing .at Detroit, county of lVayne, State ofMichigan, have invented a certain new and useful Improvement in Hydrocarbon-Burners, and declare the following to be a full, clear,

Aand exact description of the same, suchas will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. My invention relates to hydrocarbon burners, shown in the accompanying drawings and more particularly described in the following specification and claims.

As ordinarily constructed burners of this a type consist of an inner and an outer perforated chimney spaced apart and supported upon a fuel trough, an asbestos lightthat it maybe saturated with the fuel and then ignitedto convert the oil subsequently delivered to the burner into gas. An outer fuel ledge has .also been employed in some cases connected with the fuel trough, intoy which "the fuel pipe discharges.`

One o'f the objectsof the present invention is to simplify the constructiom-reduce the-manufacturing cost,-provide a burner into gas, and so construct it that it may be readily cleaned when required.

One feature of thev invention is to construct the inner perforated lower section of the chimney'l integral with the fuel trough ythat the heat may be more readily conducted thereto, theouter imperforated wall of the trough being relatively low that the trough may begreadily cleaned upon removing the router preforated chimney, the latter having an offset ledge or flange to adapt'it to be supported by the outerwall ofthe trough.

The outer perforated chimney will admit air to thelighting ring but is supported by the outer relatively low wall of the trough .out

of contact with the'fuel oil, that it may notl be coated thereby.

VAnother feature of the invention is the annular wind shield adapted to support the outer drum but whichA serves to protect the burner from side drafts, and on which rests the fuel trough of the burner.

Another feature o'f the invention consists in a centrally disposed bolt for each burner to hold the several sections of the burner to- Specieation of Letter-s Patent.

gether andv forxsecuring the burner upony a longitudinal rod or member ofthe stove :frameg-the construction being such that any number of burners may besecuredto theframe whereby a stove of anydesired size may be quickly produced.

lith the foregoing and other` objects in view which willy appear as the description proceeds, the invention resides in thelcornbination and arrangementl of parts and in.

the details ofvconstruction hereinafter described and claimed, it being understood that changes maybe made in the precise embodiment of the invention herein disclosed without departing from the spirit of the same. f Y

In the drawings accompanying this specication c Figure l is a side elevation ofan oil stove j showing a plurality of burners installed therein.

Fig. 3 is a vertical cross-sectional view through the burner secured to the inverted 'channel-iron forming part lof the stove frame. l, y j p Fig. 4 isa horizontal cross-sectional view on line 4-4 of Fig. 3.

Referring now to lthe letters of reference placed upon the drawings A, denotes an inner perforated4 Y cal4 chimney formed in sections with perforated partition walls betweeneach section.

several burners. I, denotes a centrally disposed bolt projecting downwardly through the respective sections of the inner chimney A, and also the wind guard E, of each l burner to secure the burners in spaced relation to each other upon the channel iron G gany number of burners being secured to the bar asmay be required.` J, indicates an asbestos lighting ring provided with a suitable bail J, to facilitate its removal when it is desired to ignite the oil saturating the ring. The ring J, rests upon the platform of the fuel trough B, above the depression or groove B. K, is a valve for controlling the delivery of oil through the pipe L, to the burner. f

To ignite the burner, the valve is opened Vso'that a small quantity of fuel may flow into the trough and saturate the Vasbestos ring.

A flame is then applied to the ring which causes the fuel to ignite., 'and the inner chimney'and its integral fuel trough to be quickly heated, thereby converting the liquid fuel into gas which is consumed between the perforated inner and outer chimneys.

Upon the fuel trough becoming heated sufliciently to form a gas the valve may be adjusted to admit only sufficient oil to lill the de ression or roove B-this volume of fuel is so proportioned that it ,will quickly vaporize forming a blue flame with intense heat. 1

By constructing the outer integral wall of the fuel trough relatively low, the outer chimney may be removed and the burner readily cleaned. Y

The use of the wind guard or shield E, protects the Vflame from side draft, while the perforationsin the bottom of the wind guard provide Vfor the admission of air to support combustion.

The. centrally disposed bolt I, provides a .simple means of 'securing the several sections of the burner together to form a single unit which"v may be readily secured to the channel or other suitable supporting bar of the stove flame, whereby a stove of any required number of burners may be quickly constructed.

, Having thusdescribed my invention, what I claim is l. In a hydro-carbon burner, the combination of an inner perforated chimney consisting of superimposed sections of pipe, the Vlower section of the chimney being.V provided with an integral annular trough'having. a relatively low outer wall, to permit :of ready access `to the trough, said trough having an'annular groove in its floor adjacent to its outer wall, an outer perforated chimney adapted to be supported uponV the outer wall of the fuel trough,l a wind guard consisting of an inner perforated flanged Y 2. In a hydro-carbon burner, the combin nation of an inner perforated chimney formed of superimposed sections of pipe, the lower section of pipe `constructed with an integral annular fuel troughv having. a relatively low imperforated outer wall, an outer perforated chimney adapted to be supported upon the outer vwall of the fuel trough, an annular wind guard having im-v perforated `side ,walls spaced apart with a lower connecting perforated wall for the passage of air, a bar for supporting the burner; and a central "bolt extending through the several sections of the chimney,

the wind guard, and the supporting bar, for

securing said first named partsto the supporting bar. t l e 1 3. In a hydro-carbon burner, the combination of an inner perforated chimney formed in sections Vand bridged by perforated partition wallsi, the lower section constructed with an integral Y annular fuel trough having ya relatively low'outer wall and an annular groove in the floor of the trough adjacent to the outer wall, a per-V forated outer chimney adapted tobe` su ported upon the outer wall of the troug va wind guard consisting of4 an inner imperforated flanged ring radapted tosupport` the chimney and an outer flanged imperforated ring having a perforated horizontal wall upony which the lnnerflangedring is adapted ztoirest, lacone'shaped drum supported upon the Vflanged outer wall, a .sup-'Yl porting bar for the burner, and av central bolt extending downwardlythrough the sections of the chimney and the guard to secure the several parts to the supporting bar.

In testimony whereof, I sign this( speci fica-tion in the presence of two witnesses. Y NATHAN (l. CHAPMAN.` Witnesses:
